From 0592f8f829c843ff5cb2d108c309e32f4f6f5379 Mon Sep 17 00:00:00 2001 From: Andre Przywara Date: Thu, 1 Aug 2024 12:10:54 +0100 Subject: remove wordsize.h inclusion (for musl compatibility) MIME-Version: 1.0 Content-Type: text\/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The wordsize.h header file and the __WORDSIZE definition do not seem to be universal, the musl libc for instance has the definition in a different header file. This breaks compilation of kvmtool against musl. The two leading underscores suggest a compiler-internal symbol anyway, so let's just remove that particular macro usage entirely, and replace it with the number we really want: the size of a "long" type.
